TIRE-PATCHING DEVICE.

Specification of Letters Patent.

Patented Dee. 24, 1912.

Application led July 21, 1911. Serial No. 639,771.

To all whom it'may concern: y

yBe it known that I, GUs'rAvE J. MARTEL, a citizen of the United States, and a resident of the city of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Tire-Patching Devices, of which the following is a specilication.

My invention relates to` improvements in patching devices for pneumatic tires and hask for its object the production of a device of this character which will be adapted to eectuallyserve as a tire reinforcing means and which may be yreadily and quickly arrangedL in operative position about a tire and secured in such position to the rim of the r` tire with great expedition, and which may as readily and quickly be detached when desired. A Other objects will appear hereinafter.

With these objects in viewl my invention consists in the kcombinations and arrangements of parte hereinafter described and claimed. n' l My invention will be best understood by reference to the accompanying drawings which, y Y

Figure l is a side elevation of a section of an ordinary pneumatic tire and rim to which is yapplied a patchingfdevice embodying my invention; Fig. 2 is a transverse section taken on line m-m of Fig. 1; Fig. 3 is a view similar to Fig. Vljof the lopposite side of the construction shown in Fig. 1, and Fig. 4 is a transverse section taken on line y-y of Fig. 8. i

Referring now tothe drawings 1 desig' nates an ordinary clencher rim which is provided at itsrespectiveedges with the usual engaging or clencher flanges 2. Mounted in the rim 1 is a pneumatic tire of conventional `construction, the samefbeing held in position by means of the flanges 2 in the ordinary manner. Arranged about the tread portion of the tire 8 is the patching strap 4, the latter being formed of any suitable flexible and durable material, leather or,` rawhide being preferably used. The strap 4 is of any suitable'width iny order` to'best yadapt the same to serve the purpose'for which the same is designed, thesame being' of a length preferably less than the cross sectional circumference ofthe tread portionV of the tireas clearly shown inFigs. 2`and 4.

Provided at one extremityof the strap'4 is a bar or yoke 5 of a length equalfsubstantially to the width of said strap, said bar being secured rigidly to said stra-p by means of screws 6 and nuts 7. Said bar is bowed longitudinally as shown to conform with the peripheral curvature ofthe flange 2 of the rim 1, the underside of said bar being formed, as clearly shown in Figs. 2 and 4 to conform with the conformation of thel pe-y riphery of the flange 2 against whichthe r same is adapted to abut when the device is arranged in operative position. The bar 5 is secured inoperative position to t-he rim 1 by means of hook members 8 the innerhooked ends yof said membersV 8 being adapted to releasably embrace the adjacent flange 2 as shown in Fig. 4. Thev members 8 are formed with outwardly 'projecting Shanks 9 which pass loosely through perforations 10 formedfor the reception thereof in the bar 5. Nuts 11 threaded upon the fouter endsof the Shanks 9 serve obviously to maintain the bar 5 in snugengagement'with the adjacent` surfaces of the riml and the tire 8, nut locks 11Vv ofany approveddesign being preferably when not desired. With this construction it will be observed that in order to release the extremity of the strap 4 it is only re- Vquired to remove the nuts 11, since upon employed to prevent rotation of the nuts 11 f such removal bar 5 may be slid outwardly" upon the shanks 9`to disengagement. n

Arranged at the opposite extremity of the strap 4 is a bar or yoke 12 'of a form corresponding substantially with the bar 5, the bar 12 being secured in positionby means of screws 13 and nuts 14. Arranged at the opposite side of the rim 1 that is adjacent the bar 12 is a hookmember 15 the inner hooked endof which releasably engages the adjacent engaging flange 2 of said rim. Formed yupon the member 15 is an outwardly projecting portion 16 in which are formed two transversely extending perforations 17, said perforations beingv arranged. substantially coplanar with the barr12.- The member 15 serves as a means of securing the last mentioned end of the strap 4, said member 15 being connected'with the bar 12 through the vmedium of threadedV studs 18 which depend vfrom said bar passing through the perforations y17 in said member y15. The studs 18y are detachably 'connected with the bar 12,` tapering heads 19 of said studs releasably engaging correspondingly formedsockets 20 provided for the reception thereof in said bar. Threaded upon the lower ends of the studs 18 are nuts 21 which serve obviously to connect said studs and the hook member 15, nut locks 2l being preferably employed in order to maintain the nuts 21 in position.

With the construction as set forth it Will be seen that tightening of the strap 4L about the tire may be readily effected by positively rotating the nuts 2l upon the studs 18 and loosening of said strap in order to effect detachment thereof may be eected by reversely or negatively rotating said nuts upon said studs.

A tire patching' device of the construction as set forth is durable and is of low cost to manufacture because of its economical construction. The device may be readily and quickly applied to a tire and is adapted when arranged in operative position to eifectually serve to reinforce the tire at the place Where the same is applied.

Vhile I have illustrated and described the preferred form of construction for carrying my invention into effect, this is capable of variation and modification Without departing from the spirit of the invention. I therefore do not Wish to be limited to the precise details of construction set forth, but desire to avail myself of such variations and modications as come Within the scope of the appended claims.

Having described my invention what I claim as ne7 and desire to secure by Letters Patent is:

l. In a tire patching device, the combination with a flanged rim and a tire mounted thereon, of a flexible patching strap extending over the tread portion of the tire; a bar secured to one extremity of said strap and adapted to restupon the outer periphery of the rim flange; a hook member passing through said bar and engaging one of the rim ianges; and means for securing the other end of said strap to said rim, substantially as described.

2. In a tire patching device, the combination with a ianged rim and a tire mounted thereon, of a flexible patching strap extend` ing over the tread portion of the tire; a bar secured to one extremity of said strap and adapted to rest upon the outer periphery of the rim iange; hook members having threaded Shanks passing through said bar, said hook members engaging one of the rim fianges; nuts on said Shanks; and adjustable means for securing the other end of said strap to said rim, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
